Fig. 9 is a perspective view of my invention,

Fig. 10 is a vertical cross-sectionalview taken along the line Ill-40 in Fig. 9,

Fig. 11 is a vertical cross-sectional view'taken along the line lI-H in Fig. 9,

of a modified form ill Fig. 12 is a fragmentary horizontal cross-sec-' tional view taken along the line I2l2 in Fig. 9, Fig. 13 is a perspective view of said modified form of carton with its upper cover section in a marginal tuck flaps or side marginal flap-s l9 folded downwardly from said top portion l8 and an end marginal flap 20 folded downwardly from said top portion I8 opposite the hinge 8.

The construction hereinbefore described permits rapid assembly of the tray-like lower body section 6 by folding the high endrwall lo'with the finger notch H therein upwardly, then fold-' ing the low side walls l4 upwardly causing the high end wall marginal flanges l2 and the low' side wall marginal flanges i=5 to'automatically fold inwardly to form a right angle corner of three thicknesses, the cover flap receiving pockets l6 and cover supporting ledges l-5 for the upper cover section I. The three thicknesses are then stapled together. The other high end wall I is then folded upwardly causing the high end wall marginal flanges l2 and the low side wall marginal flanges [5 to automatically fold inwardly to form a right angle corner of three thicknesses, the cover flap receiving pockets l6 and cover supporting ledges t5 for the upper cover section I. These three thicknesses are then stapled together. Obviously, the lower body section 6 can be formed by several other sequences of action.

The upper cover section 1 is formed by folding the side marginal flaps l9 and the end flap 29 downwardly.

In the assembled position, the side marginal flaps [9 of the upper cover section 1 fit in the cover flap receiving pockets 16 in the lower body section B, the inside surface of the top portion l8 of the upper cover section I rests on the cover supporting edges 13 and the end portions of the side marginal flaps 19 rest on the supporting ledges or the top edges of the low side wall [4 and the low side wall marginal flanges 5. The end marginal flap 2!! fits within the carton.

A modified form of this carton is shown in Fig. 9 through Fig. 14. This modified form of carton is similar to the principal carton with minor exceptions. The modified carton is folded from a blank 2 having scores 3, slits 4 and diagonal scores 5 therein and comprises a tray-like lower body section 6 with an upper cover section I hingedly secured thereto by means of a scored hinged 8. The lower body section 6 comprises a bottom portion9, two high side walls Ma, one of said high side walls Ma having the upper cover section I hingedly secured to the upper margin thereof, each of said high side wall-s Ma having high side wall marginal flanges i5a thereon, said high side wall marginal flanges a having cover supporting edges l3 on the upper margins thereof, and two low end walls Illa each having low end wall marginal flanges 12a thereon. The low end walls "la, the low end wall marginal flanges 12a and the high side wall marginal flanges I5a form cover flap receiving pockets l6. Staples l1 secure the low end walls Hid to the low end wall marginal flanges 2 2a and high side wall marginal flanges 15a.

The upper cover section 7 comprises a top portion hingedly secured to a high side wall Ma, marginal tuck flaps or end marginal flaps a. folded downwardly from said top portion 18 and a side marginal flap [9a folded downwardly from said top portion i8 opposite the hinge 8, said side marginal flap l9a having talbs 2| added thereto.

The lower body section 6 of this modification is formed in the manner as hereinbefore described. The upper cover section I is formed by folding end marginal flaps 29a and the side marginal flap lSa downwardly, folding the tabs 2! on said side marginal flap l9a inwardly toward said end marginal flaps 20a and securing said tabs 2| thereto by means of staples 22.

In the assembled position, the end marginal flaps 29a of the upper cover section I fit in the cover flap receiving pockets IS in the lower body section 6, the inside surface of the top portion l-8 of the upper cover section I rests on the cover supporting edges 13 and the end portions of the end marginal flaps 29a rest on the supporting ledges or the top edges of the low end wall (to and the low end wall marginal flanges IZa. The

4 side marginal flap l9a fits over and on the outn'de of the high side wall Ma of the lower body section 6.

Another modified form of this carton is shown in Fig. 15 through Fig. 19. This modified form of carton uses the same corner constructions in the lower body section B as in the principal embodiment. The lower body section 6 comprises a bottom portion 9, two high side walls Ma, one of said high side walls 14a having a finger notch H therein on its upper margin, the other having the upper cover section I hingedly secured to the upper margin thereof, each of said high side walls Ma having high. side wall marginal flanges ISathereon, said high side wall marginal flanges i5a having cover supporting edges (3 on the upper margins thereof, and two end walls [9a of the same height as the high side walls Ma, each end Wall'having a low portion 23 at the upper corners thereof, said end walls Illa having low end wall marginal flanges 12a thereon. The end walls. Illa, the low end wall marginal flanges Ida and the side wall marginal flanges l5a form cover flap receiving pockets [8. Staples 11 secure the end walls 10a to the low end wall marginal flanges [2a and high side wall marginal flanges l2.

The upper. cover section 1 comprises a top portion I8 hingedly secured to a high side wall Ma, marginal tuck flaps or end marginal flaps 20a and a side marginal flap l9a folded downwardly from said top portion [8, said end and side marginal flaps 20a and |9a being of the same height as the height of the high side walls Ma and end walls lfla so that the lower margins of said end and side marginal fiaps 20d and lBa rest on the bottom portion 9 of the lower body section 6. A finger tab 24 extends from the top portion l8 of the upper cover section 1 in cooperative relation with the finger notch H inlthe high side wall Ma of the lower body section 6.

In the. assembled position the end marginal flaps Zoo-of the upper cover section I flt in the cover flap receiving pockets IS in the lower body section 6 so that the lower edges thereof rest on the bottom portion 9 of the lower body section 6. The inside surface of the top portion I 8 of the upper cover section 1 rests on the cover supporting edge l3. The end portions of the end marginal flaps 20a rest on the supporting ledges or the top edges of the low portions 23 of the end walls Illa and the low end wall marginal flanges I211. The side marginal flap lSa fits within the carton so that the loweredge thereof rests on the bottom portion 9 of the lower body section 6.
